PROCESS OF DECORATING ART GLASS.

SPECIFICATION forming part of Letters Patent No. 718,895, dated January 20, 1903.

Application filed October 13, 1902.

T0 at whom it may concern:

Be it known that we, STEPHEN ALKE and SAMUEL A.Moss, citizens of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Processes of Decorating Art Glass, of which the following is a specification.

Our invention relates to the decorative art, and more particularly to that class of the art in which glass or other transparent material is decorated, the transparency permitting of an illumination of the design, thereby enhancing its beauty and making it more attractive. In decorations of this character a suitable surface is essential to a proper application of the colors and assists the artist in developing the painting in an artistic manner, and it is no less true that in the preparation of the decoration transparency must be borne in mind that its illumination may not be marred.

With these and other features in view it has been our aim to provide a process which will produce a simple and inexpensive decoration suitable for advertising, as well as a highly-finished painting for decorative purposes, thus giving it a wide range of usefulness.

Our process consists of mounting a print, photographic or otherwise, upon a plate of glass or other transparent material and finishing it in the manner hereinafter described. We first saturate the print with a liquid, such as turpentine, until the same is translucent, the sheet upon which the print appears being of paper or such material that it may be so rendered. The next step is to mount the print upon the plate of glass or other transparent material with its back against said plate, and this we do with varnish or like material, it having the necessary adhesive qualities to form a binder, as well as being transparent. After mounting the print upon the plate as described we rub it down with a penetrating and slow-drying oil having an affinity for colors, such as sweet-oil, for giving a surface best adapted to paint on, thereby assisting the artist to obtain the most effective results. Turpentine having an attinity for both oil and varnish, the saturation of the print with turpentine assimilates the oil upon one side, and the use of varnish on the other side binds the print to the plate, and at Serial No. 127,175. (No specimens.)

the same time the oil and varnish, which do not assimilate well,are separated by the print. Having thus mounted the print upon the plate and prepared the face of the print in the manner described, it is then colored as desired, and for this purpose we employ washes of oil colors in a vehicle such as turpentine. To form a moist surface on which to do the coloring and permit the use of turpentine in the coloring, we use oil in rubbing down, it having an affinity for the turpentine, and yet by reason of its being slow-drying gives sufficient time for the artist to do the work before the colors set.

It will be seen that inthe preparation and mounting of the print, as well as in the preparation of the surface for painting and applying the colors, we have employed materials that will maintain the transparency of the decoration, so that its beauty may be more completely brought out by illumination.

When the decoration is completed in the manner described, if desired it may be pro teeted by a transparent covering in any wellknown manner.

Having described our process, what we claim for our invention, and desire to secure by Letters Patent, is-

The process of decorating, which consists in the employment of a print on material capable of being rendered translucent, first saturating the print with a liquid having an affinity for both colors and binder, to render the sheet on which it appears translucent, then mounting said print on said plate with its back against said plate by a binder such as varnish having affinity for the saturating material, then rubbing down said print with a penetrating, slow-drying oil having an affinity for colors, to form a surface for the coloring, and finally coloring the same by washes of oil colors in a thin vehicle, substantially as described.

In testimony whereof we have hereunto set ourhands this 11th day of October, A. D. 1902.
